Check brake system light on, ABS light on, audible warning; brakes seem to work fine but not sure if ABS still enabled.
abs light comes on sporadically when applying brakes. also feel a pumping sensation in pedal and a noise at same time which causes volt meter to temporarily begin discharging. unknown cause to problem. taking to mechanic for diagnosis.
ABS light and brake light stay lit up
new brakes and rotors installed all around. Brake system emits a farting sound when depressed at low speed right before the stop. I also get a traction control light when first going forward from reverse.
ABS and Brake warning light comes on at any given time. Not fix because no one can tell me the real problem. Some shops say it is sensor and some say it is the module.
ABS LIGHT COME ON AND STAY ON WHEN DRIVING. SOMETIMES IT WOULD AFFECT THE BRAKING.
Entire Life of Vehicle since NEW ... GM has had vehicle in their shop almost if not more than 20 times, three of which was for almost a month straight each time and they still have not corrected the problem. Now that it has exceeded warranty, GM will not fix chronic problem anymore when they never truly fixed it in the first place. This causes a Stabilitrak issue and loss of power as well as spasming of the vehicle and has been a danger to me and my family for years but we cannot afford a new payment at this time besides I love this vehicle except for this repetitive issue!
My ABS light and warning siren would activate intermittently, starting about 3 years ago. We replaced a wheel bearing/ABs unit that appeared to have worn/failed, but the problem persists. It appears to be the main control unit. My car failed inspection this past month due to it, although braking is not effected at all.
abs light and brake light is on, the truck backs up easy but hard to pull off
ABS light come's 0n when driving on ice in 4 wheel drive.
The ABS light goes on once and awhile. The brake pedal will pulsate and make noise at the same time. It seems to be stopping okay but not sure if the ABS is engaging?
Abs and brake lights on. Can't figure outnidsye
ABS light and loud auditory warning whenever I drive the vehicle. We have replaced one of the ABS sensors on the front passenger wheel, since beating needed to be replaced to pass inspection. Still didn't help problem.
